ABOUT YOUR MT110-103 2
MT110-103
8X8 Mono Audio Matrix Switcher
The MT110-103 is a Balanced Audio Matrix
Switching Card. This card allows any input to be
independently switched to any or all of the outputs.
All inputs and outputs can be wired for unbalanced
audio, or they can be wired for balanced audio
allowing longer cable runs and superior noise
resistance. Additionally, the MT110-103 has
variable gain for each output.
As a “transparent” distribution amplifier, this card
utilizes AC coupling on its inputs for ideal signal
transfer characteristics. Switching is controlled with
easy-to-use ASCII commands from a control
system or computer connected to the RS-232 port
of a MultiTasker enclosure or from the keys
programmed on the front panel of the MultiTasker.
Each card uses two slots in a MultiTasker
enclosure, and all input and output connections are
accomplished via captive-screw terminal blocks.
Although designated as an 8x8 matrix switcher, the
MT110-103 can be used in a variety of ways to
provide different capabilities. For example, one 8x8
card can handle mono audio while two 8x8 cards
handle stereo audio, or a single 8x8 card can be
used to create a 4x4 stereo audio matrix.
The HelpInside™ feature allows programmers to
have access to command structures and control of
the MT110-103 from any terminal using the [HELP]
command. In conjunction with ALTINEX’s unique
command structure, HelpInside™ provides
easier-than-ever control of MultiTasker cards with
simple keyboard commands. No typing of long
keyboard strings is necessary.

INSTALLING YOUR MT110-103 6
Step 1. Turn off power to the MultiTasker
enclosure.
Step 2. Slide the MT110-103 into an available slot
in the MultiTasker enclosure in order to
connect to the bus. Make sure that the
MT110-103 card fits into place. Secure
the card to the MultiTasker by tightening
the retainer screws located on the top and
bottom of the card.
Step 3. Connect audio cables from the audio
sources to the input connectors of the
MT110-103. Connect the output
connectors of the MT110-103 to the audio
equipment through high-quality audio
cable.
Step 4. Starting from the left, identify the slot
number where the MT110-103 card is
plugged into the enclosure and note that it
is for RS-232 control.
Step 5. Turn on power to the MultiTasker
enclosure.
Step 6. The LED on the card panel will turn red
indicating that the card is in full operation.
OPERATION 7
7.1 RS-232 CONTROL
The MT110-103 has many advanced
remote-control capabilities accessible through
standard RS-232 communication. Control may be
accomplished through a computer, control system,
or any device capable of RS-232 communication.
7.1.1 RS-232 INTERFACE
The control commands for the MT110-103 are in
a simple ASCII character format.
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
3. Spaces are not legal characters.
The cards in a MultiTasker are capable of
performing various functions, as well as
providing feedback to the user or control
system. Commands instruct a card to perform
specific actions or request information from the
card. Some commands do both simultaneously.
A command that instructs the card only to
perform an action will generate feedback of “[ ]”.
The open bracket immediately followed by a
closed bracket indicates the card received a
valid command. If the command requested
information from the card, the feedback
generated by the card is the acknowledgement
of having received a valid command. Invalid
commands generate feedback that includes
“ERR” plus an error code.
Example 1: [ERR001] Error number
Example 2: [ERRC04] Card error C4
After processing a command, an “OK” or error
will be returned as feedback if “F” is included at
the end of a command string.
Commands ending in “S” will be saved into
memory. Commands not ending in “S” will still
be executed, but will not be restored when the
system is reset or powered off, then on.

7.2 DESCRIPTION OF COMMANDS
Each command consists of three parts:
Function, Card ID, and Unit ID.
[ Function , Card ID , Unit ID ]
Example: [VERC3U2]
VER = Function
C3 = Card ID or Group ID
U2 = Unit ID (optional for Unit ID 0)
For Function, see a detailed explanation under
each command description.
The card ID is a unique identifier. It is equal to
the enclosure slot number, or it may be an
assigned value. As the slot number, the value
can range from 1-4 up to 1-20 depending on the
enclosure. If the value is assigned, the ID may
be a maximum of 99. Card ID 0 (C0) is used for
the controller and cannot be reassigned.
The group ID is a number representing a group
of cards defined with the [WR] command. When
using the group ID, all cards in the group will
perform the given instruction.
NOTE: In this guide, cards are referenced by
their IDs (C1, C2...C99). Typically, the ID
number will be equivalent to the slot number.
Groups will be referenced by their IDs (G1-G8).
Changing the position of a card will significantly
affect the commands recorded on software
definitions or third-party control systems.
The unit ID has a range from U0 to U20. U0
should be used for single unit operation. If the ID
is set to U0, each command may be used
without Ui. Use the command [SETU0], as
explained in the MT101-101 User’s Guide.
Example:
[VERC3]: For U0
[VERC3Ui]: For ID other than U0
[VERC3]: Equivalent to [VERC3U0]
COMMAND ORGANIZATION
The RS-232 commands in this section are
organized into the following 5 categories:
Basic Commands
Feedback Control
Card Control
Volume Ramping Controls
Card IDs
Groups
See the SUMMARY OF COMMANDS (Section 7.3)
for one-line descriptions of each command.
BASIC COMMANDS
The basic commands are used to provide general
information about the card. These commands are
most useful during the initial stages of setting up
and operating the card.
1. [VER]
This command displays the software version
and card type for the card.
Command Format: [VERCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
Send the command [VERC4] to check the
version of the MT110-103 in slot 4. The system
will return the following feedback:
[MT110-103 690-0152-011 C04]
MT110-103 = model number
690-0152-011 = software version
C04 = card ID
MULTITASKER
400-0197-006

2. [C]
This command receives the status of the card.
Command Format: [Cn]
Cn = card ID (n = # from 1 to max slots)
Example:
There is an MT110-103 card in slot 4. Sending
the command [C4] to the MultiTasker will yield
feedback similar to the following:
CONFIGURATION:
Matrix:8x8, In-Offset=0, Out-Offset=0
CONNECTION OUTPUT VOLUME
In01-Out01 ON 32/32
In02-Out02 ON 32/32
In01-Out03 ON 32/32
In01-Out04 ON 32/32
In01-Out05 ON 32/32
In01-Out06 ON 32/32
In01-Out07 ON 32/32
In01-Out08 ON 32/32
In this example, Input 1 is connected to all
outputs except for Output 2, which is connected
to Input 2. All outputs are turned on.
The volume level for each output is shown next
to its connection. The maximum level is 32 out
of 32 which is equal to a gain of one.
If there is no card in slot 4, sending the [C4]
command will not return any feedback.
3. [CnS]
This command saves the input to output
connections, on/off status and output volume
settings for each output. The saved
configuration will be restored after the system is
reset or powered off, then on.
Command Format: [CnS]
Cn = Card ID (n = # from 1 to max slots)
S = Save configuration
Example:
If Input 1 is connected to all outputs, but only 1
through 4 are on, the feedback after sending the
command [C4S], for slot 4, would be similar to
the following:
CONFIGURATION:
Matrix:8x8, In-Offset=0, Out-Offset=0
CONNECTION OUTPUT VOLUME
In01-Out01 ON 32/32
In01-Out02 ON 32/32
In01-Out03 ON 32/32
In01-Out04 ON 32/32
In01-Out05 OFF 32/32
In01-Out06 OFF 32/32
In01-Out07 OFF 32/32
In01-Out08 OFF 32/32
[SAVED]
4. […S] – SAVE
This command saves the configuration
command being sent in memory. When sending
the command [I1O1C4S], after reset or power
up, Input 1 will be connected to Output 1 on C4.
This command only saves the Input 1 to
Output 1 connection above. In order to save all
the current settings, use the [CnS] command.
5. [CLR]
This command clears the card, restoring the
default settings. In this case, Input 1 to all
outputs, all outputs on and all input levels to
maximum.
Command Format: [CLRCn]
Cn = Group ID (n = # from max slots)
Example:
Clear the card in slot 4 by sending [CLRC4]. The
card in slot 4 is now set to its default values.

6. [TEST]
This command performs a series of tests on the
internal memory of the card.
Command Format: [TESTCn]
Cn = Card ID (n = # from 1 to 99)
Example:
Test the internal memory of the MT110-103 in
slot 4 by sending [TESTC4]. The card will
respond with feedback similar to the following:
MEMORY IS GOOD
Otherwise, failures would be indicated in the
feedback from the card.
7. [HELP]
This command displays information available for
the MultiTasker interface commands.
Command Format: [HELPCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
In order to display the RS-232 commands
available for the MT110-103 card in slot 4, send
the command [HELPC4]. The commands along
with a brief description will be displayed.
FEEDBACK CONTROL
The next commands are a function of both the card
and the front panel and allow flexibility over when
and how card information is displayed.
8. [FBD]
This command turns feedback delay on or off. It
is necessary when installing some newer cards
in older systems. If the system does not receive
all of the feedback from the card, the card may
be communicating too fast. This command will
slow down the card's communication rate.
Command Format: [FBDm]
m = Delay (0= no delay, 1= delay 100mS)
Example:
The command [HELPC4] is sent to the card in
slot 4. Some of the HELP file is displayed on the
screen, but most is missing. Send the command
[FBD1] to slow down the rate at which the card
sends feedback to the system.
9. [?]
This command displays general information
about a MultiTasker and its installed cards.
Command Format: [?Ui]
Ui = Unit ID (i = from 0 to 20)
Example:
A MultiTasker with unit ID 1 has a front panel
with part number MT101-101 and contains an
MT103-122, MT103-123, and MT110-103. Send
the command [?U1] and receive the following
feedback:
[(MT101-101U1)(MT103-122C01)
(MT103-123C02)(MT110-103C04)]
MT101-101U1 = Panel number/unit ID
MT103-122C01 = MT103-122 is in slot 1
MT103-123C02 = MT103-123 is in slot 2
MT110-103C04 = MT110-103 is in slot 4
10. [?C]
This command displays general information
about a card and its status.
Command Format: [?Cn]
Cn = Card ID (n = # from 1 to max slots)
Example:
The MT110-103 in slot 4 has Input 1 connected
to all outputs and all outputs are on. Send the
command [?C4] to receive feedback status
similar to the following.
[(MT110-103C04)(VR690-0152-011C04)
(ON11111111C04)(MA0101010101010101C04)

MU0C04 = Mute status
The ON/OFF status line is read from left to right
as Outputs 1-8. A "1" indicates the output is on
and a "0" indicates the output is off.
The matrix connections are also read left to right
representing Outputs 1-8 and the input to which
each is connected. The first two digits show the
input number to which Output 1 is connected.
The third and forth digits are for Output 2 and so
on.
The matrix configuration is the size of the matrix.
In this case, the matrix has 8 inputs and 8
outputs.
The output volume settings are read left to right
representing Outputs 1-8 and the volume to
which each is set. The first two digits show the
volume level for Output 1. The third and forth
digits are for Output 2 and so on.
11. [STA1]

This command immediately connects inputs and
outputs previously set with the PATH command.
The command switches all paths set on this
card and all other cards in the enclosure. See
the examples for the [ON] and [OFF]
commands.
21. [OSI]
This command sets the input offset value that is
applied to all inputs. The default is zero, or
Input 1 equals Input 1.
Command Format: [OSImCi]
m = Offset (m = # from 0 to 128)
Ci = Card ID (i = # from 1 to max slots)
Example:
[OSI16C4] sets the input offset to 16 for C4. The
inputs on C4 will now be their physical number
plus the offset value. In this case, Input 1 would
now be Input 17.
22. [OSO]
This command sets the output offset value that
is applied to all outputs. The default is zero, or
Output 1 equals Output 1.
Command Format: [OSOmCi]
m = Offset (m = # from 0 to 128)
Ci = Card ID (i = # from 1 to max slots)
Example:
[OSO16C4] sets the output offset to 16 for the
C4. The outputs on C4 will now be addressed by
the value of their physical number plus the offset
value. In this case, Output 1 would now be
Output 17.
23. [VLO]
This command sets the absolute volume level
for a given output.
Command Format: [VLOmAvCn]
m = Output (m = # from 1 to 8)
v = Volume Level (v = # from 1 to 32)
Cn = Card ID (n = # from 1 to max slots)
Example:
There is an MT110-103 card in slot 4. Set the
output volume of Output 2 to 16 by sending the
command [VLO2A16C4].

24. [SEL]
This command is the output select command. It
sets the path to adjust the output volume level
for the current matrix. It is used in conjunction
with the [ + ] and [ - ] commands.
Command Format: [SELmCn]
m = Output No. (m = # from 1 to 8)
Cn = Card ID/slot number
Example:
An MT110-103 is in slot 4. Adjust the volume on
Output 2. The current value is 10, but after
sending the following commands, a level of 15 is
obtained:
1. [SEL2C4]
The current output level is 10.
2. [ - ] [ - ] [ - ]
The level is now 7 and is too low.
3. [ + ] [ + ] [ + ] [ + ] [ + ] [ + ] [ + ] [ + ]
The level is now 15 and no further
adjustments are required.
25. [ + ]
This command increments a selected property
to be adjusted from the keyboard or front panel.
Command Format: [ + ]
[+] = Increment level by one-step
Example:
See the [SEL] command example.
26. [ - ]
This command decrements a selected property
to be adjusted from the keyboard or front panel.
Command Format: [ - ]
[-] = Decrement level by one-step
Example:
See the [SEL] command example.
27. [MUT0]
This command turns on the all the outputs
without changing other settings.
Command Format: [MUT0Cn]
Cn = Card ID (n = # from 1 to max slots)
Example:
Send the command [MUT0C4] to enable the
outputs for C4.
28. [MUT1]
This command turns off all the outputs without
changing other settings.
Command Format: [MUT1Cn]
Cn = Card ID (n = # from 1 to max slots)
Example:
Send the command [MUT1C4] to mute all the
outputs for C4.
VOLUME RAMPING COMMANDS
The following commands are used to control the
volume of the MT110-103. They may be used with
computer control or from the front panel with the
{SETVK} command. The following code sample
sets front panel keys 8 and 10 to Ramp Up and
Ramp Down respectively. See your Front Panel
User’s Guide for more details.
When defined as a volume control key, the key will
respond to two conditions: press and release.
Below, subroutine 8 starts ramping up when key 8
is pressed. Subroutine 10 starts ramping down
when key 10 is pressed. Subroutine 108 stops
ramping when either key is released.
Since there are multiple outputs on this card, the
output to ramp must first be selected using the
[SEL] command. For example, send [SEL2C4] and
then [RDNC4] to ramp down the volume level on
Output 2 of C4. Then, send the [SEL2C4] and
[RUPC4] commands to ramp the level back up.

respond with the following feedback:
[31][30][29]…[16]
35. [RST]
This command stops ramping and maintains the
last volume setting. It can be used as a
stand-alone command, or as a volume key on
the front panel. As a volume key, the ramping
action begins when the key is depressed and
then stops when the key is released. See the
code sample at the beginning of the volume
ramping section.
Command Format: [RSTCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
The card in slot 4 is ramping from 1 to 32 at a
rate of 32 steps in 18 seconds. Send the
command [RSTC8] and the card will stop
ramping. The last displayed volume setting will
remain the current volume level.
36. [RAMP]
This command displays the ramping time for 32
steps. The time between each step is equal to
the time in seconds divided by 32.
Command Format: [RAMPCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
Display the ramp rate setting for the card in
slot 4 by sending the command [RAMPC4]. The
system will respond with feedback similar to the
following:
RAMPTIME = 6 SECONDS
MULTITASKER

37. [RAMP=x]
This command sets the ramp rate for 32 steps.
The range is from 4s to 18s, in 2s steps.
Command Format: [RAMP=xCn]
x = Rate in Seconds
4 = 0.13 seconds/step
6 = 0.19 seconds /step
8 = 0.25 seconds /step
10 = 0.31 seconds /step
12 = 0.38 seconds /step
14 = 0.44 seconds /step
16 = 0.50 seconds /step
18 = 0.56 seconds /step
Cn = Card ID (n = # from 1 to max slots)
Example:
Send the command [RAMP=16C4] to set the
ramp rate to 16 seconds. Ramping will occur at
a rate of 32 steps in 10 seconds, or 0.50
seconds per step. Confirm the setting by
sending [RAMPC4] and receiving the feedback:
RAMP TIME = 16 SECONDS
ID COMMANDS
The default card ID is the same as the card slot
number. The next several commands allow the
user to change the card ID to a value other than the
slot number. Once the ID is changed, moving the
card to another slot will not change the card ID. If a
card in slot 4 is set to ID 1, then moved to slot 10,
its ID will remain 1. The [RSI] command forces
each installed card to take its slot number as its ID
number, regardless of the slot in which it is
installed.
Some cards require more than one slot in the
MultiTasker system. As an example, some matrix
switcher cards require 4 slots. If 5 of these cards
are installed, they would be numbered C4, C8,
C12, C16, and C20. Changing the ID allows the
user to define the cards as C1, C2, C3, C4, and C5.
Another use for changing the card ID is to be able
to use multiple systems without having to set each
unit to a different unit ID. All systems may be left as
unit ID 0 for ease of programming. The cards in the
first unit may be numbered 1-10 and in the second
unit 11-20.
38. [RSI]
This command resets the card IDs in the
system. After sending this command, each card
ID in the system will match the slot number of
the card. If the card is moved to another slot, its
ID number will be the new slot number.
Command Format: [RSI]
Example:
Send the command [RSI] to the system with
Unit ID 0. The card in slot 1 will have ID 1, the
card in slot 2 will have ID 2, and so on. If the
card in slot 1 is then moved to slot 4, the card ID
will then be 4.

39. [SIDn]
This command sets all the cards installed in the
MultiTasker system to the same card ID. After
sending this command, all cards will be
addressed with the same ID. Use caution when
sending this command to a system with multiple
board types.
Command Format: [SIDn]
n = Card ID (n = # from 1 to 99)
Example:
Send the command [SID1] to the system. All the
cards in the system now have ID 1. Any
commands that are sent to card ID 1 will be
received and executed by each card.
40. [SIDnCi]
This command sets the card ID of a single card
to a number from 1 to 99.
Command Format: [SIDnCi]
n = Card ID (n = # from 1 to 99)
Ci = Slot Number (i = # from 1 to max slots)
Example:
Send the command [SID50C10] to set the ID of
the card in slot 10 to an ID of 50.
41. [SID+]
This command sets the card ID of all the cards
in a system to their slot number plus the offset
value.
Command Format: [SID+n]
n = Offset amount (n = # from 0 to 99)
The maximum card ID is 99, so subtract
the highest slot number from 99 to find
the maximum offset. For example, in an
8-slot enclosure, the maximum offset
would be 91. The slot number (8) plus the
offset (91) equals 99.
Example:
There are two 20-slot enclosures to be
connected together during normal operation.
The first unit will use the default IDs where the
card ID is equal to the slot number. The second
unit will have the same unit ID, but each card ID
will be offset by 20.
Connect the computer to the second unit only
and send the command [SID+20] to set the ID of
all the cards in the second enclosure to their slot
number plus 20. Reconnect both units to the
computer.
The cards in the first unit will be referenced as
card IDs 1-20 and the cards in the second unit
will be referenced by card IDs 21-40.
42. [RSN]
This command displays the slot number of a
card with a specified ID number. If more than
one card has the same ID, each slot number will
be displayed.
Command Format: [RSNCi]
Ci = Card ID (i = # from 1 to 99)
Example:
The card in slot 4 takes up four slots in the
enclosure. Its ID was set to 1 since it is the first
card installed in the system, reading from left to
right. Send the command [RSNC1] to find the
slot number of this card. The system responds
with the following feedback:
